Detecting Malicious Traffic on Your Network - Seguridad Mania.com - España y América Latina

Too often, when looking for malicious network traffic you either search for known bad or investigate anomalous traffic that doesn’t look normal. That reactive approach is time consuming, and potentially over-reliant on searching for larger concerns. Fortunately, new solutions use advanced analytics to proactively identify, enrich and alert on malicious traffic. Why is this important? Detecting known bad traffic is great when it works, but it’s a lot like signature-based AV (which is rigid and unable to detect unknown threats): **Only really effective for widespread, generalized attacks – not so great for unique targeted attacks **There’s an indefinite amount of time before the malicious traffic signature, domain name or IP makes it into the pattern updates and threat intel feeds from your vendors **Detecting anomalous traffic can address the aforementioned weaknesses, but in practice it depends heavily on how – and how well – you define anomalous traffic, and how quickly (accurately) you can spot it. Security practitioners are getting better by the day at looking for anomalies. Here’s just a few: **Protocols **Unrecognized port protocol numbers **Malformed/non-compliant traffic compared to protocol expected on known port **Protocols you don’t want or at least don’t expect to see in the given context **High bandwidth usage for that protocol **Traffic patterns **Disproportionate inbound/outbound bandwidth usage for a given endpoint **Suspicious Destination/Source IP combinations In this real training for free event, we will explore how to analyze your network so that you can learn and understand its traffic patterns and get a handle for what’s normal. You’ll then be able to take this information and look for anomalous traffic, build known-bad detections and make your network detection and response (NDR) technologies and efforts smarter.
